"Thus," when the closing medium is in position, the'eiitire periphery of the axial opening-12 will be overlapped and the-openerids ofthe-body' allel :to'the channel ll-and preferablyent iiely through the projection 1% in alongitudinal direction. The. cross-Sectional width of the said projection is preferably less than the V cross-seotional wvidth of the body 10 and ispreferably gir ranged in the center of said body which thus extends equally to each side thereof.

my invention..- It will readily be seen that. for instance any ofthe forms of block illustrated in the parent application above referred to may be substituted i n 'carrying out my ar 'angemcnt as described hereinafteln.

In constructing a floor or-ceiling according to my improvement the blocks are set up on the customary temporary sca fi'olding in such a manner that the longitudinal axes of adjacent blocks extend zit-substantially right angles to each other. In other words, the side walls of oneblock 'are'loc'atcd between and opposite to the open ends of two adjacent blocks as can clearly'be seen by refer-ring to Fig. 2. of the drawings and so as to be spaced from said open ,ends, the flanges 15 if used serving as a medium for spacing the blocks and as a bottom for the space therebetwcen. In this condition the closing means and side walls of the blocks will form thevertical walls of channels 16 which cross each other and extend preferably parallel to each'other in two di,rections Reinforcing rods 17 may be placed in these" channels 16 so asto extend lengthwise thereof, said rods being anchored' in and supported by the walls of the building inthe usualmanner. Afton the-reinforcing rods lfl'have been placed in position concrete orother coalescent material 18 is introduced intosaid channels so as to' fill the same'and in some cases also to cover the upper surfaces of the blocks. The said coalescent 'material will firmly bind the blocksinto a solid monolithic structure and will form girders or beams ol' great strength and rigidity. If the specific form of block illustrated in the drawings is used the projections 14 will intcrrnpt the coalescent material "-18 which covers the upper surfacesof each block to each side of its projection 14. ,Some of the coalescent material will enter the channels 14: so that the resulting girder or beam of coalescent material will have substantially the form of a 'T in cross section and. will consequently have a maximum power to resist strains of any kind. 1 The coalescent material is prevented by the-end closing means from reaching-the interior of the bodies 10 and also serves to. securelylock said end closing means in operative position.

A very light and extremely strong and durable floor or ceiling of great carrying and resistingyunvrr is secured with my construction, which floor or ceilingis also absolutely fire proof.

As before stated the particnlanform of block shown herein has only been adopted to illustrate the invention and is only one of many forms which may be used in carrying out my arrangement. It is also to be understood that mcansor devices other than the flanges 15 may be used to form bottoms for the cross-wise extending channels 16.

The principal idea embodied in the pres ent invention is that of placing open ended blocks at an angle to each other andspaced apart in such a manner that the side walls of the-blocks together with the means for closing saidopen ends form the vertical walls of channels which cross each other and serve to accommodate reinforcing rods and coalescent material as described.

Various changes in the specific form and arra'ingement shown and .described may be made within the scope of the claims-without departing from the spirit of my invention.

I claim: 1. In a floor or ce ling construction, a

pluralityof open ended -blocks spaced from each other. to form intersecting channels,

and arranged with the axes of adjacent blocks extending at an angle to each other, a coalescent material in said channels and means for preventing said coalescent ma- Y plurality of open ended blocks spaced apart to form intersectingchannels, and arranged with the axes of adjacent blocks extending at an angle to each other, closures for closing the open ends of the blocks, and adapted together with the side walls of the blocks to form the walls of said channels, reinforcing rodsin said channels and a coalescent material in said channels covering said reinforcing rods. l

i. In a floor or ceiling construction, a plurality of open ended blocks arranged with the axes of adjacent blocks extending at angles to each other and with a side wall of a block spaced from the open end of an adjacent block, closures arranged to close the open ends of'said blocks and adapted. together with said side walls to formthe walls-of channels, means for spacing said blocks apart and arranged to form the bottoms of said channels and a coalescent material in said channels.

ia'cent block, closures arranged to close the open ends of said blocks and adapted to gether with said side Walls to form the walls of channels, flanges extending along said blocks' for spacing them apart and for forming the bottoms of said channels and a coalescent material in said channels. I

6.. In a floor or ceiling construction, a plurality of open ended blocks arranged with the axes of adjacent blocks extending at angles to each other and with a side wall of a block spaced from the open end of an adjacent block, closures arranged to close the open ends of said blocks and adapted to gether with said side walls to form the walls of channels, flanges extending along said blocks for spacing them apart and for forming the bottoms of said channels, reinforcing rods in said channels and a coalescent material in said channels'covering said reforcing rods.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
